BH 4 -substituted argyrodite solid electrolytes are mechanically softer and achieve near-theoretical density at lower pressures room temperature compared to Cl- or Br-substituted counterparts, which is consistent with nanoindentation test results.
In ferritic steels, solute carbon (C) causes two types of discontinuous stress fluctuations that are accompanied by local deformation bands in the stress–strain curves. One is yield drop with Lüders band at yielding, and other serrated flow Portevin–Le Chatelier (PLC) during strain hardening stage, is, PLC effect. can be explained static aging dynamic aging, SSA DSA, respectively. These difference mechanics distinguish qualitatively explain when they appear curve yielding strain-hardening...
SEWGS 공정에 사용하기 위해 개발된 두 종류의 <TEX>$CO_2$</TEX> 흡수제(PKM1-SU, P4-600)에 대해 가압 회분식 유동층 반응기를 사용하여 각 흡수제의 반응성에 미치는 조업변수의 영향을 측정 및 해석하였다. PKM1-SU 입자와 P4-600 입자 모두 흡수-재생 반복횟수가 증가함에 따라 흡수능이 감소하는 경향을 나타내었으며 흡수능력 측면에서는 입자가 우수한 성능을 나타내었으나 재생반응온도와 재생반응속도 것으로 나타났다. 입자는 스팀농도가 증가하였으나 입자의 경우 스팀농도 5%에서 10%로 증가한 후 거의 일정한 나타내었다. 흡수제 최종 재생온도가 증가하는 15 bar 이상에서는 압력이 흡수능력이 급격히 The Effects of operating variables on reactivity two absorbents (PKM1-SU and P4-600) for process were investigated in a pressurized fluidized...
Cu precipitation behavior of a Cr-Ni-Mn austenitic stainless steel containing small amount during aging between 923 and 1023 K for up to 24 h was investigated by atom probe tomography with cluster-finding interfacial segregation analyses. At K, started at 20 min aging, forming uniformly dispersed nano-sized precipitates the number density reached maximum 2 although volume fraction continued increase increasing time h. The precipitate size steadily increased temperature. growth rate observed...
In this study, the effect of microstructural factors on impact toughness hypoeutectoid steels with ferrite-pearlite structure was quantitatively investigated using multiple regression analysis.Microstructural analysis results showed that pearlite fraction increased increasing austenitizing temperature and decreasing transformation which substantially decreased interlamellar spacing cementite thickness depending carbon content.The usually as or decreased, although largely associated...
