Impact Testing of Metals

Abstract Impact testing of metal experiment was conducted by performing Charpy V-notch impact tests and the ductile-brittle transition temperature of the three metallic samples was established. Three samples of metals were studied ( 1018 hot-rolled steel, brass and aluminum) to assess the Charpy V-notch impact energy as a function of temperature and the ductile-brittle transition temperature. The DBTT for the sample tested were recorded as follows: -109F, 32F, 71F, 140F and 205F respectively. From the results obtained, it is evident that the fracture energy varies with the original temperature of the specimen under investigation. For Steel, the highest fracture energy ...

Introduction

For one to achieve success in any given casting practices, there must be a proper control in the variables required during the process. The variables may involve certain characteristics of the alloys, and metals used, the casting method, design of the mold, material of the die used, and the parameters used during processing. The casting quality is influenced by the cooling rate, gating systems, and the evolved gasses during the entire process. Precautions must be, therefore, taken to avoid defects during metal casting design. This paper also outlines the economic factors that are relevant and basic in casting operations.
