WebThe yield point in well-oriented fibers is in the range of 0.5%–1.0% strain, whereas isotropic samples show a yield strain at about 2.2%. Unloading the fiber after the first extension up to a strain larger than the yield strain results in a small but permanent extension of the fiber.

WebResults show that the yield point is caused by precipitate pinning. Furthermore, precipitation is enhanced by pre-strain, which can be introduced by elevated- temperature working, rapid cooling, or tensile elongation at room temperature. Aging is effective between 400 and 760 deg C, depending on the type of pre- strain, iron content, and texture. WebIn materials scienceand engineering, the yield pointis the point on a stress-strain curvethat indicates the limit of elasticbehavior and the beginning of plasticbehavior. Below the yield point, a material will deform elasticallyand will return to its original shape when the applied stressis removed.
