In the first harvest, AVG application in multiple doses provided fruits with higher skin rupture strength
values in relation to control treatment fruits and those that received only pre-harvest ethephon application, but with no difference between fruits that received pre-harvest singledose AVG application and multiple-dose AVG combined with ethephon.
(2) The creep rupture strength
of the cast alloy exhibited no difference to that of the wrought alloy, because the inhomogeneous microstructure of the cast alloy between dendritic and interdendritic regions contained secondary particles that dissolved during long-term creep.

Rheological characteristics: Rheological characteristics like firmness, rupture strength
, and elasticity were measured on starch gels prepared through micro-visco- amylograph which were poured in 3.5 cm internal diameter plastic bowls, covered with parafilm, and stored in refrigerator.
Generally, these specimens exhibited greater ultimate failure strengths than the specimens in other groups such that longitudinal grooves showed enhancement of the ultimate rupture strength
to a considerable degree compared to conventional surface preparation.
This model is a modified version of the Goodman-Boiler mean stress model (13), which has a form similar to the Modified Goodman equation (1), bui using creep rupture strength
as opposed to the ultimate tensile strength.
The rupture strength
test was executed on a quasi-static tensile testing machine Housefield H100K with the suitable fixture indicated in Fig.

Developed in conjunction with Oak Ridge National Laboratory, Tenn., consultant Anthony Martocci, Bethlehem, Pa., and Mittal Steel USA, Chesterton, Ind., IC-221M has nearly 5x the yield strength and nearly 1.5x the creep rupture strength
of current stainless steels used in furnace rolls.
has received a patent for making a plastic-coated metal plate for an automobile exterior plate, which comprises adhering or pressing a plastic film or sheet on both faces or one face of a metal plate, on a surface of the metal plate either directly or with only adhesive interposed there between, the plastic film or sheet having a surface tension at least 30 mN/m, an elongation percentage at break of at least 30% at a tensile rate of 20 mm/minute/20[degrees]C and a rupture strength
of at least 1000 kg/[cm.sup.2] at a tensile rate of 20 mm/minute/20[degrees] C.
With a transverse rupture strength
equal to that of C7 cemented carbide, it offers the potential to replace carbide in roughing and finishing aluminum.
Pertinent Data: The X500 features an advanced substrate and coating combination that increases transverse rupture strength
(TRS) up to 25%, which allows for faster cutting feed rates and greatly increases parts per edge.
