Rapid Thermal Processing to Enhance Steel Toughness

Thermal Model of Rapid Thermal Processing Systems

Continuously shrinking device parameters and the enlargement of wafer diameters in semiconductor industry require best temperature homogeneity in Rapid Thermal Processing (RTP). This together with the requirement of high ramp rates in the range of 200 °C s as advantageously used in ultra shallow junction processes [1] challenges temperature control in RTP technology. In order to design advanced...

Rapid thermal processing of magnetic materials

The rapid thermal processing (RTP) technique features dynamic control of temperature, which permits high heating and cooling rates that cannot be reached with conventional furnace treatments. In recent years, RTP has been increasingly applied to the processing of magnetic materials. The controllable heating profiles provide an approach for the deliberate construction of materials structure via ...

Size distribution of oxides and toughness of steel weld metals

The trend in strong weld metals is towards microstructures dominated by low carbon martensite. The role of oxide particles introduced into the metal during welding then becomes uncertain. The particles do not seem to affect the nucleation or growth of martensite. This is probably because this phase forms at relatively large driving forces and therefore does not rely on heterogeneous nucleation ...

Glassy steel optimized for glass-forming ability and toughness

An alloy development strategy coupled with toughness assessments and ultrasonic measurements is implemented to design a series of iron-based glass-forming alloys that demonstrate improved glass-forming ability and toughness. The combination of good glass-forming ability and high toughness demonstrated by the present alloys is uncommon in Fe-based systems, and is attributed to the ability of the...
