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 the 14th Five Year Plan, China clearly proposes to develop automobile strategic industry, reduce carbon emission intensity, and formulates peak plan by 2030. As is most frequently used vehicle, weight reduction can achieve purpose of energy-saving help emissions as soon possible. The lightweight steel research hotspot in future, has attracted much attention manufacturing industry. Fe-Mn-Al-C...

In order to obtain the bulk brick like samples, the mixture of steel slag, and sintering aid additive (like dolomite, glass, perlite, borax and phosphate sodium) were sintered at 1100°C for 2 minute. The flat and bloated surface appearances were obtained. The bulk densities of final sintered composites were from 1.3 to 2.41 g/cm3 and total porosities were from 15 to 40%. The bending strengths v...

The gas flows through the low permeable porous media are of great interest, especially in vacuum technology for filtering, separation processes, protection, and flow control. They can combine a high mass rate level rarefaction. transient experimental technique, developed previously measurements microchannels [Rojas Cardenas et al., Phys. Fluids 23, 031702 (2011)], is generalized to obtain perme...
