the unique properties of air-cooled bainitic steels have been described. a series of mn containing air-cooled bainitic steels invented by authors is presented in this paper: including low carbon granular bainitic steels, low carbon grain-boundary allotriomorphic ferrite/granular bainite duplex steels, medium and medium high carbon bainite/martensite duplex steel, and low carbon carbide free bai...

Libya is an important oil country particularly to European countries. The combustion products of fossil fuels are causing great damage through pollution, acid rains and the greenhouse effect. Hydrogen can be stored in three different ways, as a gas, as liquid, as a material and metal hydrides. Low alloy steels have been widely used in different scale welded structures. The mechanical properties...

In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN ...
