Hoffman and published by . This book was released on 1968 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to obtain experimental indications of the relative merits of surface replication, extraction replication, and thin-film methods as currently used at Lewis to evaluate the microstructures of dispersion-strengthened materials. The conclusions of this study, based on two types of materials whose finest resolved particles were of the order of 100 Angstrom (0. 01 micrometers), were as follows: surface replication gave the best agreement of measured and nominal amounts of oxide whether the oxide was discrete and spheroidal (i. e., nickel + thorium, dioxide (Ni + ThO2)) or plate-like and aggregated (i. e., aluminum + aluminum oxide (Al + Al2O3)); this method was also felt to give the most satisfactory value of average particle size (PS) and average interparticle spacing (IPS). Extraction replication was also satisfactory for the former material but not for the latter; the validity of the extraction method was dependent on the shape of the oxide particles and its state of aggregation as well as the effectiveness of the extraction technique. The thin-film method was helpful in verifying the existence of the finer particles but gave considerably greater volume fractions of oxide particles compared to the respective nominal amounts: For the Ni + ThO2 the calculated IPS decreased, while for the Al + Al2O3 not even an apparent PS or IPS could be calculated because of particle aggregation and/or overlap. Particle-size - frequency distributions obtained from each of the three methods when applied to the Ni + ThO2 essentially agreed. Stereoscopic, or three-dimensional, views of thin films gave better indication of the shape of the particles and the spatial relations between particles. Under some conditions, stereoscopic views can thus supplement and/or provide cross checks on surface or extraction replication.
