Lower quenching temperatures create microstructures that demonstrate a greater elasticity, with smaller and less brittle connections forming between microstructures.
12) Martensite is a high-carbon steel formed from the rapid cooling of austenite in a process that does not allow carbon to diffuse out of the heated metal. Tempered Martensite has reduced hardness but increased toughness, and the metal is partially decomposed into ferrite and cementite by the tempering process.
13) Yes; there are some limited applications where the brittleness of quench-hardened steel will not pose a significant barrier to use. In most applications, however, tempering is required after quench hardening in order to reduce brittleness and increase the toughness of the steel.
14) Furnace: All heat shields must be in place, and the area in and around the furnace must be kept clear of all dust, debris, and other equipment. Ventilation paths must be substantial and remain free from blockages, and indicators in the area should clearly show when the furnace is on. Izod Impact Testing Machine: Ensure safety is on the pendulum arm whenever first...
Engineering Curriculum Content Engineering curriculum Acquiring Engineering education is essential in training good quality engineer who afterwards becomes equipped to take up challenging task and responsibility as they undertake their duty. As one who is bestowed with responsibilities of administering an institution with limited resources and assigned to take part in revising the engineering curriculum that can accommodate more number of graduates, it is important to have necessary curriculum contents. As time passed
Engineering Ethics Ethics and Morality Related to the Field of Engineering The purpose of this paper is to define engineering ethics in brief, here the discussion will also be about why successful engineers should be able to inspire trust and confidence in others where their integrity and honesty is concerned. Some references will also be given regarding why college students have to be loyal before they step into the practical world. All
2009). This gives a strong idea of where the ethical onus lies in the practice of engineering. Another rather more expansive case study can be derived form the current state of bridges in the United States, and the general state of disrepair of many bridges that are still n regular heavy use (Harris et al. 2009). A rating system has been developed that determines when a bridge should be put
When you begin a career, you may not be sure what skills you are lacking, so working part-time, taking an internship, or even volunteering could help prepare the student for what the job entails, and make them more comfortable as they begin their career. As the career develops, the engineer may begin to see skills that are lacking, such as English writing, or team building, or many other aspects of

Engineering Ethics This post-mortem report is directed to the British Petroleum (BP) board of directors concerning the BP Texas City refinery explosion incident that took place on March 23, 2005. A series of explosions occurred during the restarting of the hydrocarbon isomerization unit in the Texas City refinery. The main technical reason behind the initial explosion was the flooding of the over-pressurized distillation column, which ended up in a geyser of
