Sliding abrasive wear when combining WEDM conditions and polishing treatment on H13 disks over 1045 carbon steel pins

Effect of Heat Treatment on Mechanical Properties of H13 Steel

This paper reports results of in-house experimentation on heat treatment and mechanical testing of H13 tool steel. Heat treatment strategy practiced by the industry is described in detail. Effect of various types of heat treatment on fracture toughness, hardness and other mechanical properties is also analyzed. It was found that toughness (expressed in terms of plane-strain fracture toughness K...

Nanoscale Abrasive Wear of CoCrMo in In Situ TEM Sliding

The mechanical behaviour of materials at nanometre dimensions has been a major recent topic of research. In this study, the wear properties of a *60-nm thin foil made of the ductile fcc phase of a CoCrMo alloy were examined using in situ sliding test in a transmission electron microscope by sliding a silicon AFM tip on the fcc matrix under an applied normal load of 416–1,279 nN. The material ne...

Superplasticity of Annealed H13 Steel

H13 steel is a widely used hot work die material. A new type of hot working method is imperative to develop complex and precise dies. In this paper, the heat treatment of H13 steel (AISI) was carried out by annealing, the final structure is a point or spherical pearlite, and the grain size is about 30-40 μm. The tensile properties of the annealed microstructure were investigated at 650, 750, an...

Modeling of Polishing Mechanism in Magnetic Abrasive Polishing

Magnetic Abrasive Polishing (MAP) is a super-finishing process primarily used for polishing of nonmagnetic and hard materials like, ceramics and stainless steel. This paper deals with the detailed parametric study in polishing of stainless steel work surface. Statistically designed experiments based on Taguchi methods show that size-ratio, tool-work surface clearance, polishing speed, magnetic ...
