Abstract: mechanical properties of AISIH 13 hot-work tool steel have been studied. Cast samples made of the modified new steel were homogenized and austenitized at different conditions, followed by tempering at the specified temperature ranges. Hardness, red hardness, three point bending test and Charpy impact test were carried out to evaluate the mechanical properties together with characteriz...

in this work, effects of homogenization time of 3 to 13 h at 1200 °c on the grain refinement of as-cast aisi 301 stainless steel after different hot rolling conditions were investigated. the results showed that the minimum grain size of 16±7 mm was achieved when homogenization took place at 1200 °c for 9 h followed by hot rolling at temperature range of 1000–1200 °c with strain of 0.8 and strai...

the hot charging of continuously cast slabs steel is usually considered an effective method to reduce theenergy consumption in the hot rolling mills. in this work the application and optimizing of hot charging ofcontinuously cast slab in mobareke steel company has been investigated. mathematical relationship betweenthe cooling time of the stack of slabs and its mass average temperature is descr...

H-13 steel surface was duplex-treated using Plasma Nitriding (PN) and PVD coatings to solve the thermal fatigue problem faced in die-casting applications. Chromium-based multilayer CrN/Cr (m-CrN) multi-component aluminium–titanium-based AlTiN (m-AlTiN) were deposited a cathodic arc deposition technique after plasma nitriding with different case-depths of 50 µm 200 µm. The structural, tribologic...

Die casting process is used since long, but even today problems like erosion, corrosion, soldering and sticking affect die life. These dies undergo thermal cyclic loads from 70 oC to 600 oC during processing. Physical Vapor Deposition (PVD) hard coating can play an important role in such extreme applications. In the present work, we report the use of Chromium based multila...
