Directional casting
WebFeb 23, 2024 · 7. Hello, I recently switched from the built-in render pipeline to the universal one and I noticed that directional lights look significantly worse now. A directional light in the built in render pipeline would cast perfect hard shadows, but in the universal render pipeline that is no longer the case. Even with a Shadow Resolution of 4096, hard ... Directional solidification (DS) and progressive solidification are types of solidification within castings. Directional solidification is solidification that occurs from farthest end of the casting and works its way towards the sprue. Progressive solidification, also known as parallel solidification, is solidification that starts at the … See more Most metals and alloys shrink as the material changes from a liquid state to a solid state. Therefore, if liquid material is not available to compensate for this shrinkage a shrinkage defect forms. When progressive solidification … See more Directional solidification is the preferred technique for casting high temperature nickel-based superalloys that are used in turbine engines of … See more • Campbell, John (12 June 2003), Castings (2nd ed.), Butterworth-Heinemann, ISBN 0-7506-4790-6. • Wlodawer, Robert (1966), Directional solidification of steel castings, Pergamon Press.
