Exciting metallurgical breakthroughs of the last decades alongside development and wide-ranging availability new more capable experimental theoretical tools for metals research demonstrate that we are witnessing dawn a age in design. Historically, discovery metallic materials has enabled vast majority key engineering advances human history. Current challenges create an urgent need to further ou...

Metal additive manufacturing (AM)-fabricated high-strength aluminum (HS-Al) alloys (2xxx, 6xxx, and 7xxx) tend to produce fatal metallurgical defects such as porosity cracks. Since Al is the most important lightweight structural material in automotive aviation industries, successful printing of HS-Al high demand. Therefore, this review focuses on formation mechanisms research advancements addre...

Environmentally and technologically sulphur is a deleterious constitute in coal which makes it unsuitable for use in metallurgical industries unless the sulphur level can be reduced to the tolerable limit. Characterization of the various forms of sulphur and their associations in coal is an essential issue to find and propose a suitable desulphurization method. In this research, to evaluate sul...

Rare earth (RE) magnets have become virtually indispensible in a wide variety of industries such as aerospace, automotive, electronics, medical, and military. RE elements are essential ingredients in these high performance magnets based on intermetallic compounds RECo5, RE2TM17 (TM: transition metal), and RE2TM14B. Rare earth magnets are known for their superior magnetic properties—high inducti...

The production of nuclear fuel used in the research reactor at Instituto de Pesquisas Energéticas e Nucleares (IPEN/CNEN-SP) requires a series of chemical and metallurgical processes. The quality of the end product depends on the control over all the stages of the manufacturing process and over the quality of raw materials employed. In fact, spectrometric methods are increasingly used as quanti...

In this investigation, special consideration was given to observe the influence of the acquired ultra-fine-grain (UFG) structure through friction stir processing (FSP) on mechanical and damping properties. As the mechanical behaviour of the composites are intensely related to their microstructure. For deeply understanding the possible mechanism and detailed microstructural observations at a lon...

Arsenic in dust and aerosol generated by mining, mineral processing and metallurgical extraction industries, is a serious threat to human populations throughout the world. Major sources of contamination include smelting operations, coal combustion, hard rock mining, as well as their associated waste products, including fly ash, mine wastes and tailings. The number of uncontained arsenic-rich mi...

Welding of dissimilar magnesium alloys and aluminum alloys is an important issue because of their increasing applications in industries. In this document, the research and progress of a variety of welding techniques for joining dissimilar Mg alloys and Al alloys are reviewed from different perspectives. Welding of dissimilar Mg and Al is challenging due to the formation of brittle intermetallic...

AbstructA new extraction algorithm for the metallurgical channel length of conventional and LDD MOSFET’s is presented, which is based on the well-known resistance method with performing a special technique to eliminate the uncertainty of the channel length as well as to reduce the influence of the parasitic source/drain resistance on threshold-voltage determination. l n particular, the metallur...
