Unreal Engine 4 supports many different blending functions that you can use when blending between animation poses and transitions.
An example of a Custom curve used to Blend between different poses.
You can select from many different blending functions: Linear, Cubic, Hermite Cubic, Sinusoidal, Quadratic, Circular, Exponential and Custom. For most types, you can separately control whether you want easing on either the in or the out of the curve.
The Custom option requires a Curve Float asset. After creating one, you can assign it in the Details panel for the relevant nodes:
This will allow you to specify just about any blend you want to perform. The length of the curve will be normalized and scaled down to meet the specified blend time and any values that are outside of the range 0-1 are clamped back to fit. If a Custom curve is not specified the system will fall back to a Linear blend as depicted below.
