| 1 | Polycrystalline diamond compact with enhanced thermal stability显示文摘Polycrystalline diamond compacts(PDC), which are composed of diamond and WC/Co substrate, and synthesized at high pressure and high temperature(HPHT), are widely applied as the tooth of drilling bit. However, the thermal stability of PDC will be reduced when diamond transforms into graphite due to cobalt in PDC acting as a catalyst during the drilling work. In this study, a new three-layer structured PDC with enhanced thermal stability has been successfully synthesized at pressures of 5.5–7.0 GPa and temperatures of 1650–1750?C. In this structure, the diamond-Si C composite acts as the working layer,and the diamond-Si C-Co composite and WC/Co cements are as the intermediate layer and substrate,respectively. It is found that the initial oxidizing temperature of the three-layered PDC is enhanced up to820?C, which is significantly higher than that(~780?C) of the conventional PDC counterpart. | Shiqi Liu Lei Han Yongtao Zou Pinwen Zhu Baochang Liu | 2017 | Journal of Materials Science & Technology2017，33，11： | 5 |

| 4 | Twinned Martensitic Substructure in a Water Quenched Fe–1.0 wt%C Alloy显示文摘A Fe–1.0 wt%C alloy was quenched into water from 1100 ℃,leading to lath martensite and plate martensite of body-centered tetragonal structure.Both these two martensites have the twinned substructure that generates mirror symmetric diff raction patterns with extra diff raction spots around n/3(112).The twinned substructure has the origin from twinned martensitic variants,namely twin-related crystals separated by{110},rather than{112}<111>deformation twins.Tetragonality eff ect on the electron double diff raction of twinned variants was discussed. | Haidong Sun Zuohua Wang Shuai Zhang Ning Liu Pinwen Zhu Dongli Yu Hongwang Zhang | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，7： | 0 |
| 5 | {112}<111>Twins or Twinned Variants Induced by Martensitic Transformation?显示文摘Twinned substructure in lath martensite was induced in the interstitial free(IF)steel via a high pressure thermal cycle(heating up to 1100℃and holding for 30 min,cooling at 10℃/s to room temperature under a pressure of 4 GPa).Experimental observations and theoretical simulation confrm that the twinned substructure has the origin related to the twinned variants rather than the bcc{112}<111>twins,while extra difraction spots were caused by crystal overlapping rather than any extra phase.The diferences in crystallography and electron difraction behavior between twinned variants and{112}<111>twins were discussed in detail. | Zuohua Wang Haidong Sun Peng Wang Ning Liu Pinwen Zhu Dongli Yu Hongwang Zhang | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，1： | 0 |
