Abstract
Employing 0.14 per cent carbon steel, temperature and stress dependences of minimum creep rate and steady state creep rate in secondarv stage of creep are studied with particular reference to the characteristics of primary stage creep. The results are presented and discussed in terms of the empirical expression of creep behaviour of the material. The strain rate in secondary stage of creep is directly related with that of primary stage creep at arbitrary time. It facilitates the prediction of the characteristics of long term creep from the data of short term creep tests. Overall relation between strain rate, temperature and stress in secondary stage of creep is presented in the new "Master creep curve", which is established by taking applied stress on ordinate and new parameter including the properties of primary stage creep on abscissa.
