EVALUATION OF POROSITY IN ALUMINUM INGOT |
摘要 |
Porosity of aluminum ingot can be evaluated using focused beam ultrasonic testing and/or florescent dye penetrant testing. The aluminum ingot can be machine cut to form an aluminum ingot slice prior to testing. The machine cut can be performed using a polycrystalline cutting material in a “fly cutter” configuration. The polycrystalline cutting material can comprise a diamond material. The insert can cut an aluminum ingot slice to a surface roughness finish in the range of about 7-9 micro inches. |

1. A method of evaluating porosity of an aluminum ingot sample comprising the steps of: cutting the aluminum ingot sample to form an aluminum ingot slice, whereby the cutting is performed using a diamond cutting insert as a fly cutter to produce an aluminum ingot slice; and subjecting the aluminum ingot slice to fluorescent dye penetrant testing. |
