Ivestigation on the thermal stress fatigue behaviour of steel 3cr2w8v
鋼熱應力疲勞探討 -
Abstract : the process of thermal fatigue crack propagation on the surface of steel bonded carbide gjw35 under the action of thermal stress has been observed
文摘:觀察了在熱應力作用下gjw35鋼結硬質合金表面熱疲勞裂紋擴展過程。 -
Thermal and welding residual stress often produces in the proceeding of the electronic package, the residual stress release and thermal deformations of the microelectronics will reduce the assemble intensity between the chip and package, and then debase the electrical performance of the assemble circuit, numerous thermal cycling will lead to thermal fatigue or thermal failure of the microelectronics
電子封裝器件在生產的工藝過程中，往往會產生熱殘余應力以及焊接殘余應力，殘余應力的釋放作用及器件在使用過程中的熱變形，會降低集成電路晶元與封裝體的結合強度，進而降低集成電路的電性能，反復的熱循環，將導致器件的熱疲勞失效，嚴重時可導致矽片或陶瓷片破裂，使整個器件遭到破壞。 -
The choice of laser output window height is relation to many factors, such as pressure loading, thermal loading, yield stress, influence on wavefront, failure by fatigue. spherical windows can endure higher laser intensity. however, it brings some phaseshifts, which connect with laser windows parameters
激光器輸出窗口厚度的選取與壓力載荷、熱載荷、材料極限強度、厚度對波前的影響、材料疲勞等多種因素有關，由於球殼窗口能承受較高的功率密度，但窗口本身帶來相移，該相移大小與窗口參數有關，根據位相均方根值選擇球殼窗口參數。 -
Thermal stress fatigue
熱應力疲勞 -
The thermal fatigue resistance of al2o3 - 20wt. % tic is the best, it is due to high kic and pore of the material. the pore decrease the stress extension of tip of cracks and delay themal shock fatigue cracks extension. 4
含20wt . tic的復合陶瓷具有高的k _ （ 1c ）和較多的孔隙，這些空隙在熱震疲勞時降低熱震疲勞裂紋尖端的應力集中並阻礙裂紋擴展從而提高了材料的斷裂抗力，故其具有最好的抗熱疲勞性能。
