Microstructural Development in HSLA-100 Steel Weld Metals. (1998)
Light microscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) have been employed to examine the decomposition of austenite in high-strength low alloy 100 steels. The...
Microstructural Development in HSLA-100 Steel Weld Metals. (1998)
In order to check the validity of the data from the as-received plate samples were re-austenitized, quenched and subsequently tempered for up to 3 hours at 605 deg C. In order to document the long...
Included in this report are the preliminary findings concerning the investigation on the nature of spray formed aluminum-silicon carbide based metal matrix composite. In light of the fact that grain...
The aging response of an 8090-SiC composite at 190 deg C has been monitored using microhardness tests, macrohardness tests and transmission electron microscopy(TEM). Intriguingly, it has been found...
An Investigation on the Two-Stage Strengthening Behavior of an Al-Li-Cu-Mg-Zr Alloy. (1998)
Song, Shihong, Zhang, Weibin, Cheng, Jun, Ryba, Earle R., Howell, Paul R.
Tensile properties were determined on an Al-2.2Li-2.2Cu-1.5Mg-0.12Zr alloy. The results indicate a two-stage strengthening behavior caused by precipitation reaction and changes in the grain and...
Nakayama, Masaru, Howell, Paul R.
A study on the effect of cooling rate after solution treatment on the structure and tensile properties of aged aluminum alloy 2090 is presented. Results indicate that the tensile strengths (ultimate...
Varughese, Rajan, Howell, Paul R.
Microstructural changes in low carbon hsla-100 containing copper have been investigated with the aid of tem and optical microscopy. martensitic microstructures that developed in the simulated...
