This document studies the process parameters for diffusion bonding of titanium to stainless steel 304 and aluminum 6061. Diffusion bonding is a solid-state joining process that occurs through atomic transfer at the interface when materials are bonded under heat and pressure. The key parameters that influence bonding are temperature, time, and pressure. Experiments explored bonding titanium to stainless steel at 900°C for 90 minutes at 5MPa and bonding titanium to aluminum at 450°C for 90 minutes at 10MPa. Microhardness tests found these parameter combinations produced the highest bonding strengths at the interfaces. Optimization of diffusion bonding parameters is important for joining dissimilar metals like titanium.

Study on laser hardening parameters of ASTM Grade 3 pure titanium on an angle...Premier Publishers
This research paper includes the laser transformation hardening of commercially pure titanium sheet of 1.6mm thickness is investigated using CW Nd:YAG laser. Commercially pure titanium has prevalent application in various fields of industries including the medical, nuclear, thermal, marine, defense, automobile aerospace and pharmaceutical industries. A FFD with RSM is employed to establish, optimize and to investigate the relationships of three laser transformation hardening process parameters: laser power, scanning speed, and focused position on laser hardened bead profile parameters such as angle of entry of hardened bead profile and power density. RSM is used to develop pseudo-closed-form models from the computational parametric studies. Adequacies of developed models were analyzed by ANOVA. Effects of laser process parameters on an angle of entry of hardened bead profile and power density were also carried out using RSM. The laser power and scanning speed consecutively have a positive and significant effect on angle of entry of hardened bead profile and power density respectively as compared to the focal point position among all laser hardening process parameters. The optimum laser hardening conditions are identified sequentially to minimize an angle of entry of hardened profile, power density. The validation results demonstrate that the developed models are accurate with low percentages of error.
Mechanical Properties Of Fibre Reinforced Concrete Subjected To Elevated Temp...IJARIDEA Journal
The impact of high temperature on the break property of solidified cements which are strengthened with steel and polypropylene filaments have been explored inside the extent of this review. Test comes about demonstrates that higher temperature brings about lessening quality in both the filaments however with a variety in the most extreme temperature. Steel fiber strengthened cement and polypropylene fiber fortified cement is a cementitious material fortified with a given substance of discrete strands. The better mechanical property makes these filaments critical in building development and has expanded use fundamentally in view of its vitality assimilation limit. The vitality required to haul out the strands from the broke cement is more than the vitality required to split the solid grid. Hence, the vitality ingestion limit is the primary material property profited by fiber fortifications. Be that as it may, this vitality retention property holds great just up to a specific temperature. This consider was examined the present work keeping in mind the end goal to evaluate the ideal temperature up to which the quality of the solid filaments would be most extreme.

Electrospun Nanofibers Reinforced Aluminium Matrix Composites, A Trial to Imp...IJAMSE Journal
A comparison between TiO2 nanofibers and carbon nanofibers as fibers reinforced metal matrix composites with respect to mechanical properties improvements have been made in this paper. Al and Mg have been chosen as metal matrices. The used carbon and ceramic nanofibers (Titanium Oxide) were successfully synthesized using electrospinning technique. Various weight percentage of calcined
electrospun TiO2 and carbon nanofibers (1, 3, 5 and 10%) were mixed with metal matrix and fabricated by route of powder metallurgy using High Frequency Induction heat Sintering (HFIHS). Mechanical properties of the sintered composites have been investigated. The manufactured pellets were tested for compression test, hardness and microstructures by the field emission scanning electron microscopes (FESEM), which reveals the homogeneous distribution of nanofibers in the Al/Mg matrices. In addition,
energy-dispersive X-ray spectroscopy (EDS) was employed to obtain the chemical analysis of each composite. The result shows that, the ultimate compressive strength increased to 415 MPa at 5% TiO2, which is 13.5% more than the pure Al. The hardness increased up to 64% in case of using the ceramic nanofibers as reinforcement. While using CNFs as reinforcement to the Al matrix deteriorates the
mechanical properties.

Parametric study of surface roughness in turning of az31 b mg alloy under dif...Imran Sarker
A study comprising of different surface roughness parameters of AZ31B Mg alloy was done in this experiment successfully. The study was done by turning AZ31B Mg alloy under varied feed, depth and cooling condition i.e., dry, conventional flood, MQL. Different amount of surface roughness was measured by the service of a roughness tester. The collected data from the turning operation were used to analyze and get desirable results on behalf of low surface roughness. The analysis was done by means of Taguchi method and the following results were shown:
The experimentation shows that, the cutting speed has insignificant impact on the studied surface roughness parameters.
Feed rate has significant influence over the surface roughness parameters. It expressed itself as the most dominant control factor to determine a better surface roughness parameter.
Depth of cut has insignificant influence over the surface roughness parameter and it has less effect on the roughness parameters compared to feed rate.
In cutting condition, MQL emerged as the major cooling condition compared to other two conditions which are dry and flood condition.
The future study can be conducted on the investigation of tool wear and chip morphology in turning of Mg AZ31B alloy under dry, flood and MQL conditions.

Synthesis, characterization and mechanical behavior of nickel coated graphite...eSAT Journals
Abstract In this paper we are going to describe the characterization and mechanical behavior of the Nickel Coated Graphite (NCG) particle reinforced Al6061 metal matrix composite. Many a times, the composites fail to answer the question or fail to serve the purpose for which it is fabricated to. This is due to the less wetting nature between the reinforcement and the matrix and the impossibility of higher percentage of reinforcement addition in to the matrix. However, metal coated reinforcements have been able to overcome these limitations to a very extent. NCG particles reinforced Al6061 matrix with various weight percentages were fabricated by Squeeze casting method. Samples of 0, 5 and 10 wt% reinforcement addition were synthesized and characterized. Finally some useful conclusions were made. Keywords: Metal Coated Reinforcement; Nickel Coated Graphite; Squeeze Casting; Wetting.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
