摘　　要：常规方法测试材料抗高温性能时,直接对材料进行高温锻造,导致高温下材料拉伸性能、弯曲性能量化值普遍偏小。提出船舶材料抗高温性能测试方法。高温锻造前对船舶材料进行热处理,制作材料单向板,利用空气炉和烘箱,对单向板进行热暴露、淬火,通过煅烧炉,高温煅烧单向板,在不同煅烧温度下,使用拉伸机拉伸单向板,直至材料纤维断裂,得到高温下的材料极限拉伸强度、弯曲变异系数,表现材料抗高温性能。选取船舶材料中常见的Al合金复合材料,作为高温性能测试材料,实验结果表明,不同测试温度下,设计方法提高了极限拉伸强度、弹性模量测试值,反应的拉伸性能、弯曲性能更符合实际情况。When testing the high temperature resistance of materials by conventional methods,the materials are directly forged at high temperature,which results in the low quantitative values of tensile properties and bending properties.A test method for high temperature resistance of ship materials is proposed.High temperature forging to ship the material before heat treatment,making laminates have,use air stove and oven,to heat exposure,quenching,one-way slab by calcination furnace,high temperature calcination one-way slab,under different calcination temperature,using stretching machine stretching one-way slab,until the material fiber fracture,get high temperature material ultimate tensile strength,bending coefficient of variation,It shows the high temperature resistance of the material.The Al alloy composite materials commonly used in ship materials were selected as the high-temperature performance test materials.The experimental results show that the ultimate tensile strength and elastic modulus test values are improved by the design method at different test temperatures,and the tensile properties and bending properties reflected are more in line with the actual situation.
