Austenitic stainless steel is a popular material for its corrosion resistant properties, however it has low hardness which limits application. Low-temperature carburizing can be used to improve the mechanical properties of austenitic by producing expanded austenite layer. In order get high-quality layer and an efficient processing operation, process must optimized. this research, Taguchi method...

Since the sub-axis of machine tool spindles subjected to fatigue loading, the effects of different surface heat treatments on fatigue behavior of 16MnCr5 steel have been investigated in the current work. After the test specimens were prepared from the steel, the surface heat treatments; carburizing, carbonitriding and a practical type of treatment involving the first nitriding then carburizing ...
