Effects of alloying elements
{"Image DocumentName": "Effects of alloying elements", "Image ImageDescription": "(a) Alter the temperature. For e.g, 3% Ni lowers the Ac points some 30\u00b0C, while 12% Cr raises the Ac1, temperature to about 800\u00b0C. (b) Alter the carbon content of the eutectoid: The C content of the pearlite in a 12% Cr steel is 0.33%, as compared with 0.87 in an ordinary steel. Ni also reduces the amount of C in the pearlite and consequently increases the volume of this constituent at the expense of the weaker ferrite. (c) Alter the critical cooling velocity , which is the minimum cooling speed which will produce bainite or martensite from austenite.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
