Method Of Making High Strength Articles From Forged Powder Steel Alloys, Alfred A. Hendrickson, Darrell W. Smith
Method Of Making High Strength Articles From Forged Powder Steel Alloys, Alfred A. Hendrickson, Darrell W. Smith
Michigan Tech Patents
High strength steel parts or articles are made from a powder alloy by compacting the powder into a preform, sintering the preform in a sintering furnace or the like under a highly-reducing atmosphere and at a temperature of at least 1150° C., cooling the preform, preheating the sintered preform in a highly-reducing atmosphere, such as an inert gas-based atmosphere containing hydrogen or pure hydrogen, to a temperature of at least 1000° C. and transferring the preheated preform to an impact forging device and impacting the preform at a peak averaging forging pressure of at least about 1000 MPa to obtain …

Method For Compression Molding Articles From Lignocellulosic Materials, Robert D. Palardy, Bruce A. Haataja, Andrew D. Williams
Michigan Tech Patents
Flakeboard or particle board panels and other composite articles made from wood flakes or other particulate lignocellulosic materials having a relatively high internal bond and improved resistance to moisture are made from flakes or particles which have a moisture content of at least 15%. A catalyst capable of accelerating the reaction between the flakes or particles, the binder and water is applied to the flakes or particles prior to the addition of a moisture-tolerant particle board binder, such as an organic polyisocyanate. A mat of the resulting furnish is compression shaped under pressure and at a temperature less than 250° …
