Interface instability (or s̀ausaging’) has been a major problem in the oxide powder-in-tube tape-rolling process. The fast Fourier transform of core instabilities are ® rst performed to study the rolled tapes and to obtain quantitative information on the wavelengths and magnitudes of the nonuniform pro® les. The existing experimental observations are also re-examined and summarized. Treating thi...

Single-rod oxidation and quench experiments at very high temperatures in steam atmosphere were conducted with advanced, nuclear grade SiCf/SiC CMC cladding tube segments. A transient experiment was performed until severe local degradation of the sample maximum temperature approximately 1845 °C. The caused by complete consumption external CVD-SiC sealcoat, resulting access to fiber–matrix compos...

this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...

Perlakuan Panas atau biasa disebut dengan Heat Treatment, merupakan suatu proses memanaskan sebuah material (logam) temperatur tertentu dan kemudian didinginkan menggunakan media (misal: oli, air, air garam) kecepatan pendinginan yang ditentukan. Penelitian ini perlakuan panas quenching tempering pada pipa baja karbon API 5L diameter 16 inci (406.4 mm) ketebalan 1.437 (36.5 mana sebelumnya ters...

Abstract: Equal channel angular extrusion (ECAE) is a promising technique for production of ultra fine-grain (UFG) materials of few hundred nanometers size. In this research, the grain refinement of aluminium strip is accelerated by sandwiching it between two copper strips and then subjecting the three strips to ECAE process simultaneously. The loosely packed copper-aluminium-copper laminated b...

: Living-donor lobar lung transplantation (LDLLT) was first performed in the USA and thereafter it introduced Japan 1998 as an alternative modality to brain-dead donor (BDLT). Although LDLLT procedure employed for rapidly deteriorating patients who were hospitalized mechanically ventilated at time of transplantation, demonstrated better or comparable post-transplant outcomes comparison BDLT. Le...
