Laser shock hian heat-resistant steel service life a nghawng dan

Heat-resistant steel sample chu laser shock hmangin 00CR12 hmangin an tichak a, chu chu fatigue tensile test atan 25, 400, 500 leh 600℃Celsius-ah dah a ni a, heat-resistant steel sample-te mechanical property chu temperature hrang hrangah an enchhin a ni. Fatigue safety life chu unilateral tolerance factor method leh two-dimensional weibull distribution method hmangin an chhut a, laser intensification hnua sample yield strength leh elastic modulus te chu nasa takin a ti tha a, temperature a san chuan a sang chho hle tih hmuhchhuah a ni bawk. Temperature hian heat-resistant steel nunah nghawng nasa tak a nei a, boruak lumna a san chhoh zel chuan boruak hahna chu nasa takin a tlahniam a ni. Tun hnaiah laser technology hi a tlangpuiin an pawm tlangpui a, chu chuan normal temperature conditions hnuaia materials te fretting fatigue resistance a tih that theih nan a tha ber a ni.
