Microstructure and Oxidation Kinetics of Intermetallic TiAl after Si- and Mo- Ion-Implantation
Hornauer, U.; Richter, E.; Matz, W.; Reuther, H.; Mücklich, A.; Wieser, E.; Möller, W.; Schumacher, G.; Schütze, M.
Abstract
Titanium aluminide alloys based on gamma-TiAl have a substantial potential for high temperature application. However, there are still problems concerning the high temperature oxidation behavior. Ion implantation is a promising tool to improve the oxidation resistance without disturbing the mechanical properties. A systematic investigation of the microstructure and phase development of silicon and molybdenum implanted gamma-TiAl is presented. For Si, the fluence is varied from 2.5·1016 cm-2 to 8·1017 cm-2 at an implantation energy of 1 MeV resulting in a local con-centration of Si between 1 at% and 35 at% at a projected range of 1 µm measured by AES depth profiling. Grazing incidence XRD and transmission electron microscopy show the formation of a buried Ti5Si3 enriched layer at 650 °C, which acts as a diffusion barrier for oxygen. Long term TGA oxidation tests at 900 °C in air show a positive effect in the beginning of oxi-dation for the fluence of 8·1017 cm-2. After a few hours the oxidation kinetic is similar to unimplanted Ti50Al, but the mass gain after 100 h is still 30 % smaller. The influence of the local Si concentration on the oxidation behavior is discussed. Implantation of Mo at 180 keV (2·1016 cm-2 and 1·1017 cm-2) has only minor influence on the oxidation at 900 °C. After implantation, Mo precipitates are found for the high fluence.
Keywords: implantation; TiAl; oxidation; silicon; molybdenum

Zur Problematik der Bestimmung dynamischer Festigkeitswerte im instrumentierten Kerbschlagbiegeversuch
Richter, H.
Abstract
Zur Bewertung der strukturellen Integrität von Bauteilen werden auch Festigkeitskennwerte unter schlagartigen Belastungsbedingungen benötigt.
Eine Möglichkeit dynamische Festigkeitskennwerte abzuschätzen, bietet die Berechnung der dynamischen Fließ- und Biegebruchspannungen aus den nach ISO/CD 14 556 im instrumentierten Kerbschlagbiegeversuch bestimmten charakteristischen Kräften. Üblicherweise werden die Festigkeitswerte unter Schlagbiegebelastung nach einem Vorschlag von SERVER (1978) berechnet. Dieser Vorschlag wurde aus einer Lösung der Fließlinientheorie nach EWING (1968) abgeleitet.
SERVERs Formalismus gilt für ISO-V-Proben, die mit einer ASTM-Finne belastet werden, da die Zusammenhänge durch EWING (1968) für diese Belastung hergeleitet wurden. Bei Anwendung einer DIN/ISO-Hammerfinne (r=2 mm) ist aber davon auszugehen, dass sich für gekerbte Proben ungefähr 5 % und bei zusätzlicher Berücksichtigung einer größeren Stützweite 9 % höhere Festigkeitswerte ergeben können.

Use of Instrumented Charpy Impact Tests for the Determination of Fracture Toughness Values
Viehrig, H.-W.; Böhmert, J.; Dzugan, J.
Abstract
A number of techniques has been under development to estimate fracture mechanics parameters using the instrumented Charpy impact test. The evolution of elastic-plastic fracture mechanics has led to the use of small test specimens to achieve valid cleavage fracture toughness values based on the J-Integral concept, KJc, in the lower ductile-to-brittle transition temperature (DBTT) range. A successful concept bases on the statistical data treatment methodology with the Weibull-type statistic. It has been demonstrated that the probabilistic-based estimates of the median fracture toughness of ferritic steels tend to form transition curves of the same shape, the so-called "master curve", normalized to one common specimen size, namely the 1T (i.e. 25 mm thick) specimen. This method covers the determination of a reference temperature, T0, at a median fracture toughness, KJc, of 100 MPa m1/2. Furthermore toughness parameters in terms of J-Integral based ductile crack initiation toughness, KJi, have been also used for the integrity assessment of structures. The determination of KJi values by the instrumented impact test requires the detection of the ductile crack initiation on the dynamic load vs. displacement curve.
Keywords: instrumented impact test; master curve concept; fracture toughness; crack initiation; acoustic emission

Characterization of the Deformation Field Near the Crack-Tip after Bending by Small Angle X-ray Scattering
Böhmert, J.; Große, M.
Abstract
The inhomogeneous deformation field ahead the crack tip of pre-cracked and bended Charpy-V specimens was monitored by scanning with a highly focussed X-ray beam at the Synchrotron Radiation Facility (ESRF). The measured scattering pattern shows two characteristic features:
- streak-like anisotropic scattering with different symmetry
- isotropic scattering.
The results demonstrate that small angle X-ray scattering with a scanning microfocussed beam provides a new method to characterize inhomogeneous deformation states with a resolution of few micrometers.
