Description:Abstract For a quick estimation of tensile strength of cast iron, the wedge penetration test which makes measurements by breaking a disc shaped specimen with a steel wedge has come to be adopted these few years. We have already completed basic experiments on this method, and in a previous report defined wedge penetration breaking strength as the value of maximum breaking load divided by cross sectional area of specimen, and proved the method to be reliable in the foundry provided that the relationship between wedge penetration breaking strength and tensile strength is known. We have, this time, studied the mechanism of fracture from the results of wedge penetration tests under various conditions and microscopic observations of the breaking process.
