Differential Scanning Calorimetry Study of U–Cr Alloys

Abstract

The high temperature phase stability characteristics of U-xCr (x = 0, 1, 2, 3, 4, 5, 7, 9, 15 wt%) alloys have been investigated by dynamic calorimetry under slow heating (1 K min -1 ) in pure flowing Ar-atmosphere. The temperatures of various eutectic, eutectoid solid state phase transformations and that of melting have been measured as a function of Cr-content. These data are used to construct a partial U-Cr phase diagram on U-rich side, which showed good agreement with the recent assessment. The liquidus temperatures for higher Cr-contents, however exhibited a small upward shift as compared to equilibrium phase diagram estimates. The measured transformation enthalpies for the on-heating eutectoid and eutectic transformations exhibited an increase with Cr content of the alloys.

Evaluation of flexibility in pittu players

“…Playing sports is very much installed in our blood [1] . A traditional South-Asian indigenous sport named as Pittu also called as seven stone and Ellu Kallu, is very common amongst Indian children [2] . It is a strenuous contact sport and therefore many players are subjected to injury during training as well as during match.…”
