“yield strength”可以造什么句，yield strength造句

API regulates that the yield strength of flatten specimen from pipe body is used to characterized the yield strength of oil pipeline body.

The yield strength, yield tensile ratio and toughness are major quality indexes of steel pipe (board). However, it is quite difficult to determine them reasonably.

The maximum tensile strength and yield strength were gained at peak-ageing, in addition, the elongation decreased with the extension of ageing time.

The results showed that with the the increase of outside force velocity, the tension yield strength of PVC increased, but its breaking elongation decreased.

There is clearly changed on yield strength and ratio of yield and tensile strength and the main affecting elements is middle frequency heating temperature before coating.

The yield strength, yield ratio increase with the increase of annealing temperature, due to the impact of non-martensite and the decrease of movable dislocation density.

Using scaling tension test method simulated the effect of leveling elongations on yield strength ratio of hot dip galvanized dual phase steels.

Pipeline steel adopting the spicular ferrite owns the better properties of forming and anti corrosion for its low ratio of yield strength and tensile strength and uniform microstructure.

When the pre-strain surpasses 0.95%, the reverse yield strength reaches to a constant.
