Advanced Gradient Heating Facility (AGHF) ... The AGHF supports the production of advanced semiconductor materials and alloys using the directional solidification process, which depends on establishing a hot side and a cold side in the sample (a temperature gradient). It provides an extremely stable temperature environment of up to 1,400°C, high-temperature gradients of up to 100°C/cm in the solidification zone, slow movement of the gradient across a sample to provide slow growth rates, efficient cooling through the use of a liquid metal cooling ring attached to the sample container, and Peltier pulse marking capability. The AGHF consists of three modules mounted in one side of a Spacelab double rack: the Core Facility Module contains the processing chamber with the furnace inside; the Electronics Module contains the controls and equipment necessary to operate the furnace; and the Gas Storage Module contains argon for chamber repressurization and sample cooling. 2, record 2, English, - advanced%20gradient%20heating%20facility

advanced gradient heating facility: In the area of microgravity sciences and materials processing, six individual experiments, some with many separate runs, were conducted in the Advanced Gradient Heating Facility, a furnace for solidifying alloys and crystals. These experiments yielded information on the physical processes involved in solidification, and the results may help drive the production of advanced semiconductor materials in space and on Earth. 2, record 3, English, - small%20advanced%20gradient%20heating%20facility

[...] le four TITUS [a été mis en marche] pour réaliser les expériences INSITU et EQUI. Ces deux expériences étudient, grâce à la micropesanteur, les phénomènes de solidification en l'absence de convection. La solidification d’un alliage métallique est en effet un phénomène complexe. Dans un «barreau» dont les extrémités sont maintenues à des températures hautes et basses encadrant la température du point de fusion, il s’établit un front de solidification. Selon les écarts de température(le gradient), ce front peut prendre différents aspects. Pour un faible gradient de température, le front de solidification demeure pratiquement plan. Dans ces conditions, en avant du front apparaissent, autour d’impuretés microscopiques, des grains de solidification à partir desquels la solidification s’effectue dans toutes les directions. Si le gradient augmente, le front se transforme et présente des petites excroissances solidifiées(des colonnes) qui donnent une croissance cristalline cellulaire(régulière). Si le gradient est encore plus important, ces colonnes se ramifient et donne une croissance cristalline dendritique(irrégulière). L'expérience INSITU étudie plus précisément la croissance cellulaire à l'aide d’un alliage cuivre-manganèse dont le point de fusion est de 870°C. L'expérience EQUI étudie la propagation de la solidification dans toutes les directions autour des noyaux de solidification(croissance «equiaxe») en utilisant un alliage aluminium-nickel dont la température de fusion est de 640°C. 2, record 6, French, - four%20Titus
