This document provides information about metallographic specimen preparation of cast irons:
- Proper specimen preparation is important to retain the graphite phase and reveal microstructural constituents. Specimens are mounted, ground, polished, and etched.
- Grinding and polishing must be carefully controlled to avoid pulling out soft graphite. Automated preparation is recommended over manual.
- Examples show well-retained graphite in specimens that were embedded during preparation compared to pulled-out graphite in unembedded specimens.
- Final polishing with diamond suspensions on napped cloths provides the best graphite definition with minimal pullouts. Correct preparation is essential for accurate microstructural analysis of
Assessing Vapor Intrusion The Revised Astm Standard
The document discusses revisions made to the ASTM vapor intrusion standard. The original 2008 version was complicated and caused issues for meeting "all appropriate inquiries" requirements. The revised 2010 version addresses these problems by making it a guidance document rather than a requirement. It simplifies the analysis to a two-tiered screening process rather than four tiers. The revisions help clarify the "all appropriate inquiries" process and reduce confusion and costs associated with vapor screening.
Microstructural and Torsional Fatigue Characteristics of Singleshot and Scan ...
Scan and single-shot induction hardening were used to harden 1045 and 10V45 steels. Torsional fatigue testing found that while case hardness was higher in 10V45, 1045 exhibited greater ductility during crack propagation, leading to improved fatigue life. Scan hardening produced a finer prior austenite grain size and lower residual stresses than single-shot hardening. However, fatigue performance was similar between the two processes at 550 MPa stress amplitude, with single-shot showing 70% higher life at 650 MPa.
Carbon
Carbon is a non-metal element with an atomic number of 6. It can be found naturally as diamond or graphite. Diamond has a crystalline structure where each carbon atom is bonded to four other carbons in a tetrahedral structure, giving it a very hard surface. Diamond mines are located in Madhya Pradesh and Andhra Pradesh in India and diamonds are used in jewelry, cutting tools, and drilling machines.

Interpreting symbols and allegories in literature allows expanding the meaning and themes in a text.
Grain size measurement according to astm standards
This document discusses three standard ASTM methods for measuring grain size: the comparison method, planimetric/Jeffries' method, and intercept method. The comparison method involves comparing a grain structure to graded images or overlays at 10x magnification, with a repeatability of ±1 grain size number. The planimetric method counts grains within a known area at higher magnifications from 100-500x, achieving ±0.25 grain size units precision. The intercept method counts the number of grains intercepted by a test line, allowing measurement of elongated grains faster than the planimetric method at the same precision of ±0.5 grain size units.
Grain size analysis
This document provides information on sieve analysis testing of soils based on IS 2720 Part 4. It discusses the objectives of classification of soils, coefficient of curvature, uniformity coefficient, and fineness modulus. Sieve analysis is used to determine gradation of soils, mix design proportions, and filter design. The test involves sieving soil samples through a series of sieves and weighing the material retained on each sieve. Calculations are made to determine coefficients and fineness modulus.
Industrial metallurgy
Metallurgy is the study of physical and chemical behavior of metals and their alloys. The earliest evidence of metallurgy dates back 5000 years to ancient civilizations like ancient Egypt and Mesopotamia. Throughout history, metallurgy advanced with innovations like extracting copper and tin to make bronze around 3500 BC, and iron around 1200 BC. Metals are extracted from ores through processes like mining, crushing, concentration, and smelting, and shaped using techniques like casting, forging, rolling, and machining. The properties of metals can be modified through heat treatments and alloying with other elements.
Quantitative metallography
Quantitative metallography involves making quantitative measurements of microstructural characteristics from metallographic images. There are two main methods: comparison, where images are compared to standard charts, and measurement, which involves direct measurement. Measurement methods include point counting, where a grid is overlaid on images to determine phase fractions, and intercept counting, where grain sizes are estimated by measuring intercepts of grain boundaries with lines. Proper sample preparation and microscope calibration are important for accurate quantitative metallography.

It covers topics like crystalline structures of metals, phase transformations, alloying effects, microstructures like ferrite, pearlite, and martensite, and the influence of cooling rate on microstructure. It also discusses the heat affected zone and issues that can arise from changes in composition and cooling rate near the weld interface.
Cast iron
This document discusses different types of cast iron, including grey cast iron which forms flakes of graphite surrounded by a matrix, white cast iron which forms carbides rather than graphite, and ductile cast iron which contains spherical graphite nodules. It notes the main ingredients of cast iron are iron, carbon, and silicon, and that it contains more of these materials than steel. It provides examples of applications for each type of cast iron.
Grain size analysis by using ImageJ
This document provides instructions for analyzing particle images using ImageJ software. It discusses downloading and running ImageJ, processing images through thresholding, erosion, and dilation, analyzing particles to obtain size data and distribution statistics, and setting the measurement scale. The summary also acknowledges the students who provided feedback on the homework instructions.
Cast iron
Cast iron is an alloy of iron that contains 2-4% carbon, along with other elements like silicon and manganese. It is classified into gray, white, ductile, and malleable cast iron based on its composition and microstructure. Cast iron has high compressive strength but low tensile strength. It is brittle and not suitable for applications requiring flexibility. Historically, cast iron was widely used in construction for elements like bridges, columns and architectural details from the 18th century onward due to its low cost. However, it is prone to corrosion and cracking over time. Modern applications of cast iron include machine parts and components that require good castability and heat resistance.
