Abstract:

In general, the pieces that are exposed to the load in the form of a blow of hunting weapons are damaged. The damage that occurs in such parts has been determined as a result of the wrong selection of material, the appropriate unselected heat processing parameters or the unsuitable choice of geometry. The study aimed at finding the cause of the breakdown in the key part found in the fishing weapons manufactured in Turkey and of critical importance. For this purpose, the AISI 4140 and AISI 4340 low alloy steel, which are still in use in the market as material, and the AISI 1040 and AISI 1050 steel, which are selected, are intended to improve the mechanical characteristics by applying the appropriate thermal processing of these materials. The study also conducted stretching analysis using the ANSYS package program. At the end of the study, the most suitable material was normalized; the process of hardening in oil and tempering in 500C was applied to AISI 4340 low alloy steel. When the ANSYS analyses are studied, geometry has determined that there are scale accumulation areas in the piece. The need for improvement in the design to prevent this has been concluded.
