Abstract
The Effect of Annealing Temperature and Roller Burnishing on the Microhardness and Surface Quality of AISI 3115 Alloy Steel
Highlights
Some metal working process such as conventional machining methods cannot provide the optimal quality of the surface
The effect of roller burnishing on microhardness of AISI 3115 alloy steel: It can be seen from Fig. 6 that the microhardness was increased by increasing the burnishing force by range of (50-200) N for the AISI 3115 alloy steel
The effect of roller burnishing on surface roughness of AISI 3115 alloy steel: The initial average surface roughness of AISI 3115 alloy steel specimen were 1.02, 1.14, 1.2 and 1.3 that annealed at 700, 750, 800 and 850°C, respectively It can be seen from Fig. 9 that the average surface roughness was decreased by increasing the roller burnishing force over range of (50-200) N for the AISI 3115 alloy steel
Summary
Some metal working process such as conventional machining methods (e.g., turning and milling) cannot provide the optimal quality of the surface. The resulted surfaces have inherent irregularities and defects like tool marks and scratches that cause energy dissipation (friction) and surface damage (wear). Surfaces and their properties are as important as the bulk properties. The surface should be free of defects and undesirable residual stresses. There are many finishing processes used to produce surfaces with high quality. These processes could be classified into chip removal processes, such as grinding and chipless processes, such as burnishing
