Powder metallurgy method is production of parts widely used today. This use is widely used in many areas of the
steel materials industry, especially from powder metal parts produced by powder metallurgy method. Since these materials take the
form of the final product at the end of production without requiring any machining process. Also, these materials can be used as an
iron based bearing material because of the machine parts such as filter, cutting tool bits and they have self-lubricating property due
to its porosity. The aim of this study is; stainless steel matrix, boron carbide reinforcement in different ratios (5%, 10%, 15%)
is the production of functional graded material. For this reason, stainless steel and boron carbide powders were mixed in V-type
mixer for 3 hours. After this process, the samples were produced by means of powder metallurgy under pressure of 45 MPa at 900°C
in the hot press machine. The microstructure and boron carbide distribution of the produced samples were examined in the
SEM device and hardness measurements were made in order to observe the changes in mechanical properties. When
microstructures were examined, it was determined that boron carbides were distributed homogeneously. It was observed that the
hardness increased as the rate of support and the transition between the stages increased.

In the study, the AZ31 and AZ31+ La%0.2 Mg alloys were produced by low pressure casting method
following homogenization at 400°C for 24 hours and the hot rolling process applied with 15% deformation rate
per pass at 400°C. The surface treatment process of shot peening was practised on materials for enhancement
corrosion properties of them. To observe corrosion behaviour of investigated alloys the immersion corrosion test
in %3.5 NaCl environment and metallographic examination were utilized.
