Unformatted text preview: transition temperature (average) was calculated to be 34.375 degrees. Silicon Content Transition Temp where 10 J 2.55 12.5 2.85 25 3.25 37.5 3.63 62.5 Average: 34.375 Lauren Beth Beauchamp LaurenBB Tuesday, September 14, 2010 MSE 280-2B Chapter 6 Homework I believe that silicon will soften cast iron, causing it to be more ductile. I think that in a part to be used at 25 degrees you would want to use about 3% silicon to keep it’s usefulness and let it have a little give. 6-61. A tensile test measures the response of a material to a slowly applied uniaxial force. An impact test measures the ability of a material to absorb the sudden application of a load without breaking. The strain rates are much higher in impact tests versus tensile tests. Also, in impact tests the materials used usually have a notch, making the results different for each test....
