Title: Emission spectrochemical analysis of silicon in aluminum alloy
Inventor: FUKUDA MASASHI
IPC: G01N21/62
Filed: 1989-10-20
Abstract: PURPOSE:To make analysis with high accuracy by using an analysis sample controlled in the grain size of primary crystal Si to a specific size and standard sample at the time of making emission spectrochemical analysis of Si in a hypereutectic Al-Si alloy. CONSTITUTION:The emission spectrochemical analysis of the Si in the Al alloy is made by using the analysis sample and controlled in the grain size of primary crystal Si to 10 to 50mum and the standard sample in the emission spectrochemical analysis method for the Al-Si alloy contg. 13 to 30wt.% Si. The proper selection of the cooling rate at the time of solidification is merely necessitated at the time of forming the sample from the molten Al alloy in order to control the grain size of the primary crystal Si. This selection is attained by controlling cooling conditions by using a casting mold made of Al and a casting mold made of iron. The emission intensity in the emission spectrochemical analysis increases sharply with a decrease in the grain size if the grain size is below 10mum. The coarsened primary crystal Si is brittle at the time of surface cutting and is, therefore, chipped and the necessary surface finishing accuracy is not obtainable when the grain size exceeds 50mum. The emission intensity hardly fluctuates if the grain size is controlled to 10 to 50mum.

Filed: 1989-10-20
Abstract: PURPOSE:To accurately inspect the reflection strain and fluoroscopy strain of a plate type body, specially, in a curved surface shape, not to mention a plane type plate body by measuring variance in the width of a line or spot where the surface ruggedness of the plate type body is large and variance in the interval between a line and a line or a spot and a spot where the unevenness is small, and comparing the measurement result with a reference surface. CONSTITUTION:A CCD camera 4 is driven freely by a table 5 which has both an elevating and a rotating function and an electric signal obtained by photographing the entire surface of the plate type body 1 is outputted as image information to an image processor 6. Then a light-dark pattern 3 such as a grating pattern obtained at a part where surface unevenness is large such as the peripheral part of the plate type body which is bent by a gravitational bending method, etc., varies greatly in the width of the lines or spots with strain. Further, the light-dark pattern 3 obtained at the part where the surface unevenness is small varies greatly in the interval between lines or spots with the strain more than the width of the lines or spots. For the purpose, a host computer 7 processes and compares the variance with the reference value to decide whether the strain is normal or not.
