一种奥氏体不锈钢及其制备方法
摘要：
一种奥氏体不锈钢及其制备方法，基于316L不锈钢，按重量百分比计，其组分为：Al18~20%、Cr9~11%、Ni7~10%、Mo1.3~2%、Mn≤1.3%、Si≤0.6%、C≤0.02%，余量为Fe2O3；按上述组分称取反应物，原料球磨并压实后，在其表面放上引燃剂，然后置于反应容器中，通入氩气进行反应；随着温度的升高，引燃剂开始反应并释放出大量的热，引发反应物料间的反应；生成的产物在氩气保护下随炉冷却至室温制得不锈钢材料。将制备得到的不锈钢材料放入热处理炉中进行800℃~1000℃等温处理6~8小时后，得到奥氏体不锈钢材料。
摘要（英）：

The invention relates to an austenitic stainless steel and a preparation method, based on 316 L stainless steel, the austenitic stainless steel comprises the following components by weight: 18-20% of Al, 9-11% of Cr, 7-10% of Ni, 1.3-2% of Mo, less than or equal to 1.3% of Mn, less than or equal to 0.6% of Si, less than or equal to 0.02% of C and the balance of Fe2O3. The preparation method comprises the following steps: weighting a reactant according to the above components, performing ball milling on the raw materials and compacting, placing a detonator on the surface, then placing in a reaction container, introducing argon for reaction; with the rising of the temperature, reacting the detonator and releasing a lot of heat, initiating the reaction among the reaction materials, cooling the generated products in furnace to the room temperature under the protection of argon to obtain the stainless steel material, and placing the prepared stainless steel material in a heat treatment furnace for an isothermal treatment with the temperature of 800 DEG C to 1000 DEG C for 6-8 hours to obtain the austenitic stainless steel material.
