We have studied the effect of optical interference on element profiles obtained with a glow discharge optical emission spectrometer (GDS). The specimens were borophosphosilicate glass films deposited on polished silicon wafers. We found that in some cases the interference is accompanied with a beat in the profile: a damping of the sinusoidal wave followed by a recovery. Profilometry showed that the depth resolution is better when the interference continues continuously without a beat. We showed by simulation that the cause of the beat came from variation of the penetration rate throughout the sputtered area.

For fuel savings as well as energy and resource requirement, high strength low alloy steels (HSLA) are of particular interest to automobile industry because of the potential weight reduction which can be achieved by using thinner section of these steels to carry the same load and thus to improve the fuel mileage. Dual phase treatment has been utilized to obtain superior strength and ductility combinations compared to the HSLA of identical composition. Recently, cooling rate following heat treatment was found to be important to the tensile properties of the dual phase steels. In this paper, we report the results of the investigation of cooling rate on the microstructures and mechanical properties of several vanadium HSLA steels.The steels with composition (in weight percent) listed below were supplied by China Steel Corporation: 1. low V steel (0.11C, 0.65Si, 1.63Mn, 0.015P, 0.008S, 0.084Aℓ, 0.004V), 2. 0.059V steel (0.13C, 0.62S1, 1.59Mn, 0.012P, 0.008S, 0.065Aℓ, 0.059V), 3. 0.10V steel (0.11C, 0.58Si, 1.58Mn, 0.017P, 0.008S, 0.068Aℓ, 0.10V).
