    摘要:

    對(duì)Zr基大塊金屬玻璃（BMG）進(jìn)行了室溫下三點(diǎn)彎曲疲勞實(shí)驗(yàn)，旨在探究其在循環(huán)載荷下的疲勞行為。結(jié)果表明，根據(jù)確定的應(yīng)力幅度-破壞循環(huán)（S-N）曲線，Zr基BMG的疲勞極限為442 MPa。為評(píng)估P-S-N曲線，提出了一種基于最大似然原理的估算方法，利用統(tǒng)計(jì)原理預(yù)測(cè)材料疲勞壽命，減少了所需樣本數(shù)量，降低了實(shí)驗(yàn)成本。實(shí)驗(yàn)結(jié)果與美國(guó)測(cè)試和材料協(xié)會(huì)（ASTM）標(biāo)準(zhǔn)相符，證明了估算方法的可靠性和準(zhǔn)確性。

    Abstract:

    Three-point bending fatigue experiments were conducted on a typical Zr-based bulk metallic glass (BMG) at ambient temperature to investigate the fatigue behavior under cyclic loading conditions. Results show that the stress amplitude-cycles to failure (S-N) curve of the Zr-based BMG is determined, and the fatigue endurance limit is 442 MPa (stress amplitude). To evaluate the probability-stress amplitude-cycles to failure (P-S-N) curve, an estimation method based on maximum likelihood was proposed, which relies on statistical principles to estimate the fatigue life of the material and allows for a reduction in the number of samples required, offering a cost-effective and efficient alternative to traditional testing methods. The experimental results align with the American Society for Testing and Materials (ASTM) standard, indicating the reliability and accuracy of this estimation method in evaluating the fatigue behavior of Zr-based BMG.
