integrated steel making facility on the continent. Recently re-established as an independent Canadian_x000D_
company, Stelco employs more than 2,200 personnel and produces a variety of steels for the automotive,_x000D_
energy and construction sectors._x000D_
Recently, Stelco produced a hot rolled coil of a High Strength Low Alloy (HSLA) steel for a customer that_x000D_
intended to use the material to construct vehicle impact barriers (guard rails). The material needed to meet a_x000D_
demanding Drop Weight Tear Test (DWTT) specification at low temperatures. The coil was produced using a_x000D_
coiling temperature of 550 degC, but did not meet the DWTT specification and resulted in a loss for Stelco. A_x000D_
second coil was produced using a coiling temperature to 500 degC, which met the DWTT specification, but_x000D_
with mixed results. The effect of the coiling temperature on the (i) microstructure (ii) low temperature DWTT_x000D_
performance and (iii) sporadic DWTT results for this grade of HSLA steel is not well understood, and forms_x000D_
the basis of the proposed research. High resolution optical and field emission scanning electron microscopy_x000D_
will be used to quantify the effect of coiling temperature on the microstructure and damage evolution for the_x000D_
DWTT tested HSLA materials. The results will provide Stelco insight into the effect of coiling temperature on_x000D_
low temperature DWTT performance of HSLA (and similar) steel grades and benefit the company by reducing_x000D_
customer coil rejections._x000D_
Another problem faced by Stelco is associated with the DWTT test itself and how testing parameters (coupon_x000D_
thickness, notch type, test energy and shear measurement) affect the results. A parametric DWTT study will be_x000D_
conducted at Stelco's R&D facility to better understand the test and standardize their testing procedure., program purpose french : Stelco Canada is one of the top steel producers in North America, which operates the most modern greenfield_x000D_
