PLOTTING THE CURVE OF TEMPER BRITTLENESS TRANSITION TEMPERATURE BY COMPUTER

According to the different discrete degree of the testing data,three types of mathematical model are established. Then these temper brittleness transition temperature curve chart are programed by the models by VB language. The program can resolve many problems which happened by manual plotting curve chart in the produce examining. The program which has been verified by the data gained in the produce examining conforms the objective rule of the testing data and is precisly scientific and utility.
