Selected postweld transverse tensile properties for a variety of Ixxx aluminum alloys are shown in Table 5.5. Natural aging times were not reported. Although not always identihed, the failure location is most often in the soft HAZ. Transverse weld failures correspond directly with hardness minima where failure location is shown to move further into the HAZ...

Reference 2 reported on welds in 0.29C-Mn-Si-Mo-B quenched and tempered steel using a PCBN tool. Weld thicknesses included both 6.4 and 12.7 mm. Microhardness of the stir zone was found to approximately equal that of the base metal. Significant softening was observed in the HAZ. Transverse tensile properties of... 

Plate (Fig. 10). Data for 2014-T6 plate are not available for comparison thus, the 7039-T6 and -T61 comparison for plate gauges is limited to 2219-T81 (1.0-in. plate, [ ]) and 5083-0 (annealed temper) and —HI 13 (strain hardened) from previous work and the literature p ]. Figure 10 compares the transverse tensile properties (those customarily obtained on production lots of heat-treatable alloys) of 0.75-in. 7039 plate and 1.0-in. 2219-T81 plate and the longitudinal tensile properties (those customarily used in evaluating strain-hardenable alloys) of 0.75-in. 5083 plate.

It is interesting to compare the efficiency of the reinforcement for AS4 fibre in PPS and PEEK. In the former case the values are 92% and 63% for modulus and strength respectively and in the latter 99% and 87% respectively. Modulus uptake is excellent in both cases and strength in the second. The poorer strength result for PPS may be due to reduced compatibility between the fibre surface and matrix. This is supported by the lower ILSS value for PPS carbon fibre composite. Compressive properties are notably lower than tensile ones, while transverse tensile properties are similar to those of thermosetting polymer matrix materials.

In addition to the direct measurements of fiber-matrix interface properties discussed in Section 3.2, a number of testing techniques have been devised to assess the fiber-matrix interface bond quality by inference from the gross mechanical properties such as interlaminar shear strength (ILSS), translaminar or in-plane shear strength, and transverse tensile strength. These testing techniques invariably employ...

The lamina s transverse compressive/tensile properties are determined from a hoop wound (90°) cylinder loaded in axial compression and/or tension. The test methods have been standardized under ASTM D5450 and D5449. The tube geometry and manufacturing procedures are similar to those used in the lamina s in-plane shear tests.

It is shown here that alpha, beta and alpha-beta titanium alloys can be friction stir welded. The phase transformations that occur in the nugget region and the heat affected zone are discussed. Residual stresses were found to be quite high in the present work. Tensile properties in transverse direction were... 

Thread sealant tape, on the other hand, must perform after it has been applied to the pipe thread. Lower density enhances the drapability (deformation) of the tape around the threads. A balance between the tensile strength in the machine and transverse directions in the range of 15 1 d is required to achieve the desirable deformability. Elongation of 100-200 in the transverse direction and better than 800% in the machine direction are desirable. The amount of fibrillation determines the tensile properties and deformability of the tape. Too little fibrillation will yield a tape with insufficient tensile strength while too much fibrillation will create a hard tape lacking enough deformation. 

Mechanical Properties. As noted previously, caution must be exercised when interpreting strain within weldments, due to the potential for strain localization in transverse tensile tests. However, yield and tensile strength results require no special consideration. Yield strength is often related to hardness, and based on the hardness curves typically obtained for 2024 Al, yield strength as well as fracture location should correlate with the lowest-hardness location in the W -hardness curve. Mechanical properties for 2024 Al have been reported in numerous publications as a function of FSW variables, including tool rotation rate, travel speed, and sheet thickness (Ref 2,4—8,11, 15).
