摘要

摘要报告了在氩气喷射器中使用脉冲二氧化碳激光器进行等离子体辅助激光切割，激光束和光放电等离子体同时作用于材料，对铝镁锂系铝锂合金样品进行拉伸和低循环疲劳测试的结果。低循环疲劳测试表明，通过等离子辅助激光切割获得的样品所能承受的加载循环次数是通过传统连续光束激光切割获得的样品所能承受循环次数的两倍多。

MECHANICAL PROPERTIES OF AVIATION ALUMINUM–LITHIUM ALLOY SAMPLES OBTAINED BY PLASMA-ASSISTED LASER CUTTING

Results of tensile and low-cycle fatigue testing of samples made of an aluminum–lithium alloy of the Al–Mg–Li system obtained by plasma-assisted laser cutting performed by a pulsed CO₂ laser in an argon jet with the laser beam and optical discharge plasma simultaneously affecting the material are reported. Low-cycle fatigue tests show that the number of loading cycles survived by the sample obtained by plasma-assisted laser cutting is more than twice greater than the number of cycles survived by the samples obtained by conventional laser cutting with a continuous beam.
