This document studies temper embrittlement in steel samples. Temper embrittlement occurs when certain alloy steels are cooled slowly or held at temperatures from 400-660°C, resulting in decreased toughness from the precipitation of embrittling elements along grain boundaries. The study examines different types of embrittlement, remedies, and characterizes the microstructure and hardness of carbon steel samples tempered at various temperatures from 150-450°C. Hardness was found to decrease with increasing tempering temperature.
Here is a slide, which introduces basic information about cast aluminum alloys, how to name each alloy, selection rules, some example regrading of alloys from each group and their properties.
Hope you find it interesting and helps you in any way possible.
This document discusses the Rockwell hardness test. It begins by defining hardness and describing general types of hardness tests, including scratch, indentation, and rebound tests. It then focuses on the indentation Rockwell hardness test. The Rockwell test uses a specific load to make an impression and then measures the depth to determine the hardness value displayed on a dial. Several Rockwell scales exist using different indenters and loads for varying material types. The document outlines the test procedure and advantages/disadvantages of the Rockwell hardness test method.

All stainless steels contain chromium, with the chromium content exceeding 11% and being present as a solute rather than bonded with other elements. Stainless steel originated about 100 years ago with martensitic types, and advances in steelmaking technology now allow for high-chromium, low-carbon steels to be produced. The main stainless steel types are martensitic, ferritic, and austenitic stainless steels, which differ in their chemical compositions and properties.
O documento discute os tipos de metais e ligas metálicas, incluindo suas propriedades e usos comuns em construção civil, como aço, alumínio e cobre para estruturas, cabos e tubulação.
Stainless steels contain 10.5-30% chromium which forms a passive oxide layer protecting the steel from corrosion. Common types include martensitic, ferritic, austenitic, and duplex stainless steels. Martensitic stainless steels can be hardened through heat treatment while ferritic stainless steels have higher ductility and corrosion resistance. Duplex stainless steels have a mixed austenite and ferrite structure providing high strength and pitting/stress corrosion resistance. Austenitic stainless steels have excellent ductility and toughness down to cryogenic temperatures and are widely used in chemical plants and food processing. Proper welding techniques are required to prevent issues like sensitization, hot cracking, and sigma

General discussion on classification, uses of stainless steels, various causes for different problems, failures and rejects related to Stainless Steels, analysis, remedies / cures for such defects.
1) The document provides information on welding consumables and procedures for welding different types of stainless steel, including austenitic, ferritic, and martensitic stainless steels.
2) Key points covered include the composition and properties of different stainless steel types, recommendations for matching electrodes, preheating requirements, and procedures for welding stainless steel to mild steel.
3) Potential issues that can arise such as cracking, corrosion, and distortion are discussed along with ways to prevent these issues, such as controlling heat input, balancing welding operations, and using post-weld heat treatment.

The document describes the Vickers hardness test. It uses a diamond pyramid indenter to make an indentation on the material being tested under a specified load ranging from 5 to 120 kg. The indentation left has a square shape regardless of load. The diagonal lengths of the indentation are measured under a microscope and used to calculate the Vickers hardness number, providing a continuous scale of hardness values. Factors like load, indentation shape, and temperature can affect the results. Advantages include consistency of indentation shape and suitability for testing a range of materials and surfaces. A disadvantage is it takes more time than other hardness tests.
Copper is a reddish metal with a face-centered cubic crystal structure. It has high electrical and thermal conductivity and good corrosion resistance. Copper alloys include brasses, which are copper-zinc alloys that have good strength and ductility. Bronzes are copper alloys where the primary alloying element is not zinc or nickel, and include phosphor bronzes and aluminum bronzes. Copper alloys have a variety of applications due to their combinations of properties.
O documento discute os diferentes tipos de ferro fundido, incluindo:
1) Ferro fundido cinzento contém grafita em flocos, é frágil sob tensão tração, mas resistente à compressão.
2) Ferro fundido nodular/ductil contém grafita em nódulos, tem melhor ductilidade devido à matriz perlitica.
3) Ferro fundido branco contém mais cementita, é duro e frágil mas resistente ao desgaste.
O documento define metais não ferrosos como aqueles que não tem ferro como elemento principal, classificando-os em metais pesados e leves. Descreve as propriedades e usos de alguns metais não ferrosos importantes, como alumínio, cobre, estanho, chumbo e latão.
O documento descreve o processo de produção de aços, começando pela extração do minério de ferro no alto-forno, onde é produzido o ferro gusa. O gusa passa por processos para remover carbono e impurezas e produzir o aço no converter LD. O aço é então refinado e pode receber ligas metálicas antes de ser solidificado em lingotes ou barras.
This document summarizes intergranular corrosion in stainless steels and aluminum alloys. It discusses how sensitization due to heat treatment can lead to chromium depletion at grain boundaries in stainless steels, making them more susceptible to corrosion. In aluminum alloys, corrosion is localized at grain boundaries due to compositions gradients, with reactive intermetallics and copper-depleted zones at boundaries being less noble than alloyed grains. Examples show how small changes in heat treatment of aluminum alloys can switch the corrosion mechanism from intergranular to pitting corrosion. Polarization experiments on aluminum alloys indicate two breakdown potentials for corrosion initiation.
This document discusses oxide dispersion strengthened austenitic stainless steel. It begins with an introduction to stainless steels and austenitic stainless steels. It then explains how oxide dispersion strengthening works and the process used to produce these steels. Comparisons are made between the properties of oxide dispersion strengthened steels and non-oxide dispersion strengthened steels. The document also discusses the microstructure, applications, advantages, disadvantages and concludes with references.
This document defines key terms related to welder and procedure qualification including welding procedure specification (WPS), procedure qualification record (PQR), welder performance qualification (WPQ), essential variables, non-essential variables, and supplementary essential variables. It also summarizes requirements for PQR, WPS, and WPQ review and discusses validity, expiration, renewal of welder qualifications, welding repairs, and applicable Aramco engineering procedures.
The Rockwell hardness test measures the hardness of materials using indenters under specific loads. It is a quick, inexpensive, and non-destructive test that can be used to test finished parts without damaging them. The test uses a diamond or steel ball indenter that makes an impression under an initial minor load and then a deeper impression under a major load. The hardness number is read from a dial and indicates the material's resistance to plastic deformation. The test is commonly used for quality control and finding tensile strength.
This document summarizes a presentation on corrosion under insulation (CUI) and coatings for mitigating CUI. It discusses how CUI occurs due to moisture ingress under insulation and temperature cycling. Several coating types are described that can provide barrier protection for steel under insulation, including epoxy phenolic, silicone acrylic, thermal spray aluminum, titanium modified inorganic copolymers, and inert multipolymeric matrix paints. Test methods for evaluating CUI coatings like cyclic pipe tests and CUI chambers are also summarized. Real-world case studies show how some coatings have performed well under long-term cyclic service conditions.
