The aim of this study was to evaluate the effect of dissolution of the small carbides residual from annealing and earlier processing, on the mechanical and wear properties of hot-work tool steel. Recommended as well as extreme austenitization temperatures (950 °C, 1030 °C and 1150 °C) with subsequent tempering were used aiming at same hardness level of specimens of same material. This allows correlation in wear resistance variation to the microstructural elements and variations in other mechanical properties of the investigated steel. M₂₃C₆ and MC are still present at the T_aus = 950 °C, which are being dissolved with higher austenitization temperature. Optimal combination of mechanical properties are obtained at recommended austenitization. Specimens subjected to lowest austenitization showed the worst abrasive wear resistance.

热作工具钢的显微组织和力学性能对高应力磨损条件下耐磨性的影响

这项研究的目的是评估退火和早期加工过程中残留的少量碳化物的溶解对热作工具钢的机械性能和磨损性能的影响。针对相同材料试样的相同硬度水平，使用推荐的以及极端奥氏体化温度（950°C，1030°C和1150°C）并随后进行回火。这使得耐磨性变化与微观结构元素之间的相关性以及所研究钢的其他机械性能的变化具有相关性。M ₂₃ C ₆和MC仍在_金牛座上 = 950°C，并以较高的奥氏体化温度溶解。在推荐的奥氏体化条件下可获得最佳的机械性能组合。经受最低奥氏体化的样品显示出最差的耐磨性。
